  • Patent number: 6979755
    Abstract: Provided is a process for converting methane at a remote natural gas site into ethylene and other products. Methane is converted into syngas which is converted into a low-sulfur liquid hydrocarbon mixture containing less than 1 ppm sulfur via Fischer-Tropsch (FT) syntheses. The low-sulfur Fischer-Tropsch liquids are transferred from the remote site to an existing facility where a sulfur-containing compound or a sulfur-containing hydrocarbon mixture is added to avoid coking problems. The resultant blend of hydrocarbons which has a sulfur content of at least 1 ppm, is fed to a naphtha cracking unit and ethylene recovered.

  • Patent number: 6803029
    Abstract: The present invention provides a process for suppressing the formation of metal-containing coke during processing of a hydrocarbonaceous material, such as for example a hydrocarbon conversion processes. The process involves using a feed comprising CO2 and steam in combination with equipment comprising high nickel and/or cobalt alloy metallurgy including aluminum or an aluminum coating in order to reduce metal catalyzed coking at process temperatures above about 800 degrees F. The process is particularly useful in the reforming of a hydrocarbon material to make hydrogen for operation in a fuel cell.

  • Patent number: 6790547
    Abstract: The present invention provides a process for suppressing the formation of metal-containing coke during processing of a hydrocarbonaceous material, such as for example a hydrocarbon conversion processes. Electromagnetic radiation is applied to the hydrocarbonaceous material while heating the hydrocarbonaceous material to a temperature above 700 degrees F. The frequency of the electromagnetic radiation is preferably below 300 MHz. The process is particularly useful in the reforming of a hydrocarbon material for operation in a fuel cell.
